Chang Liuhang, because its is inexpensive and with excellent NVH (Noise Vibration and Harshness, noise, vibration and not
Ride comfort) performance.However, dry type PU moulding process and PP-GMT (thermoforming of polypropylene glass fiber) technique are compared, by wet type
The intensity of the inside roof lining of PU moulding process manufacture is low, weak by it and soft thus be easy to generate wrinkle on surface.
In addition, the general flow of wet-type PU moulding process is at present：1. manufacturing PU foam blocks in foaming workshop；2. by PU
Foam block cuts into sheet；3. PU foams are immersed in glue to help its molding, in the both sides of PU foams setting top layer and
Bottom is to form the inside roof lining of sandwich-like；It is molded 4. the inside roof lining of sandwich-like is put into molding tool；5. passing through
Water jet cutting process cuts into final inside roof lining.
As it can be seen that traditional wet-type PU moulding process needs additional PU foaming and cutting action, this needs large-scale workshop
With cutting machine and a large amount of manpower.Moreover, due to needing to be cut at the top and bottom of PU foam blocks in cutting action
It abandons after coming and causes largely to waste, this is because PU foam blocks are in the shape of bread-like after being formed by foam process,
Its top and bottom does not meet the shape need of vehicle liner manufacture.There was only 2/3rds usually in wet-type PU moulding process
Foam block is utilized, thus utilization rate is low.
Moreover, the structure for the inside roof lining that traditional wet-type PU moulding process is formed includes top layer, PU layers and bottom, PU
Layer is used as middle layer, and top layer includes textile surface and glass layer, and bottom includes non-woven substrates material and glass layer.
However, the glass layer in top layer and bottom since its toughness is low, gas permeability is low and sharp edge, causes it to be easy to break
Broken, NVH poor performances and the bad performance for being easy incised wound worker.
